What are the most expensive Mercedes parts to replace?

Transmission system

The transmission system helps to transfer engine power to the driveshaft and rear wheels. The gears in the transmission alter the car’s drive-wheel speed and torque, relative to the engine speed and torque. If the transmission system is damaged or has failed, you will need to change a lot of parts.

Parts of the transmission system include a hydraulic system, torque converter, planetary gear sets, torque convertor, seals & gaskets, throttle cable monitor, governor, and modulator. Replacing or repairing a Mercedes transmission system is costly. It ranges between $1,800 and $5,000, depending on the model of your car.

Catalytic converter

Catalytic converters are crucial when it comes to changing dangerous substances in the vehicle’s exhaust gases, like nitric oxide, carbon monoxide, and hydrocarbons, into less dangerous substances, such as water vapor and carbon dioxide through chemical reactions. Replacing this essential part is quite costly.

An Original Equipment Manufacturer catalytic converter from Mercedes-Benz may costs between $14,000 and $25,000. This is quite expensive, but it’s not as labor-intensive as a transmission system. Therefore, the repair cost may be slightly lower. Note that the price differs according to the Mercedes model.


A camshaft is located below the engine and offers the vital function of opening and closing the valves of an engine. It controls the engine air intake. Camshafts usually get damaged or ruined due to a lack of proper service of the vehicle. Things like skipped oil changes, dirt, and grime affect the camshaft.

Replacing a camshaft on your Mercedes-Benz car model is not only expensive, but also labor-intensive. Therefore, you should be ready to pay a lot of money for the spare part and labor. A new camshaft will cost you between $120 and $1,150.

Fuel pump

Most fuel pumps get damaged because of normal wear and tear. The work of the fuel pump is to supply the right amount of pressure to your car’s fuel injectors. If you service your car yearly, you may save your fuel injectors from getting clogged.

Car cylinder

Another expensive part that you wouldn’t want to get damaged is the car cylinder. Like the fuel pump, a damaged car cylinder usually breaks down because of a lack of proper maintenance or service. A new Mercedes-Benz cylinder will cost you from $600 and up, excluding repair costs.
